# Debates on Electrostatics #1 (All questions from H.C.V)

1. The charge on a proton is $\displaystyle +1.6\times { 10 }^{ -19 }C$ and that on an electron is $\displaystyle -1.6\times { 10 }^{ -19 }C$. Does it mean than the electron has a charge $\displaystyle 3.2\times { 10 }^{ -19 }C$ less that the charge of a proton?

2. Consider two particles A and B having equal charges and placed at some distance. The particle A is slightly displaced towards B. Does the force on B increase as soon as the particle A is displaced ? Does the force on the particle A increase as soon as it is displaced?

3. Does the force on a charge due to another charge depend on the charges present nearby?

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Sort by:

1. The charges are the same but of opposite polarity. Both will apply force of same magnitude on a unit positive charge but one is attractive an other repulsive.
2. As the electromagnetic waves travel with speed of light, so it will take a little time for force to change.
3. Not at all
